Answer:
Photosynthesis is the process of using water, carbon dioxide and sunlight to produce sugar. The process of photosynthesis requires specialized cellular structures called chloroplasts to capture energy from the Sun and converted into chemical energy.
Explanation:
D. The osculations show a variable rate of motion. Hope this helps:)
A 13-kg sled is moving at a speed of 3.0 m/s. At which of the following speed will the sled have twice as much kinetic energy?
4.2 m/s
Answer:
9.9 s
Explanation:
mass (m) = 1000 kg
initial speed (u) = 90 km/h
final speed (v) = 45 km/h
relationship between the speed (v) of the boat and the frictional force (fk) ⇒ fk = 70v
- the acceleration of the system will be given by (a) =
- acceleration is also the first differential of velocity with respect to time,
a =
- therefore acceleration (a) = =
- recall that fk = 70v
(a) = = =
(a) = =
- integrating both side of the equatin we have
t =
- the time required for the boat to slow down = t = = - 9.9 s = 9.9 s
Explanation:
Power = work / time
Power = force × distance / time
P = (12 kg × 10 m/s²) (8 m) / (10 s)
P = 96 Watts
